Kaolin calciner with lighting

Abstract

The invention discloses a kaolin calcining furnace with an illuminating lamp. The kaolin calcining furnace comprises a furnace body, temperature sensors, heating electric membrane plates, a motor, an electric control cabinet, a rotary shaft, material pushing scrapers, the illuminating lamp and a constant-current drive power supply; the illuminating lamp is an LED lamp; and the constant-current drive power supply is composed of an EMC filtering module, a bridge type rectifier module, a pulse modulation and power factor correction module, an MOS tube, a transformer and a rectifier output module. As each heating electric membrane plate is formed by butt jointing two half parts, and each two half parts penetrate through electric membrane plate mounting holes formed in the two sides of the furnace body respectively and enter an interlayer of a furnace bottom, each heating electric membrane plate is greatly convenient to maintain and change; with adoption of a mode of remote monitoring, a worker can monitor equipment without being beside the equipment; and in the constant-current drive power supply, as PFC correction and DC-DC conversion can be realized by using a single transformer, the kaolin calcining furnace has the characteristics of simpleness in circuit, small amount of elements and low cost.

Description

technical field [0001] The invention relates to a calciner, in particular to a kaolin calciner. Background technique [0002] The biggest defect of the existing kaolin calciner is that it is inconvenient to maintain, especially after the heating parts of each hearth are burnt out, the replacement is time-consuming and laborious, which brings great inconvenience to daily maintenance. [0003] In addition, the temperature of the material discharged from the kaolin calciner is relatively high, and generally it can only be bagged after natural cooling, so the efficiency is low. [0004] The existing kaolin calcining furnaces start calcining without cleaning the poor-quality kaolin, so the produced products are of poor quality. [0005] In the existing kaolin calciner, the staff must stay beside the equipment, which brings great inconvenience to the daily work of the staff. [0006] When the kaolin calciner works at night, it needs lighting. In order to save electricity, LED li...

[0004] The existing kaolin calcining furnace starts calcining without cleaning the poor quality kaolin, so the products produced are of poor quality

[0005] In the existing kaolin calciner, the staff must stay beside the equipment, which brings great inconvenience to the daily work of the staff

[0006] When the kaolin calciner works at night, it needs lighting. In order to save electricity, LED lights are generally used. At present, the power factor correction (PFC) of the driving power used for LED lights is generally realized by an independent transformer. The constant current is realized by using a single 431 or two 431 or stable diodes; therefore, the PFC correction circuit used in the traditional drive power supply is more complicated, the number of components is relatively large, and the cost is high; and the output constant current accuracy is not high, generally within 3 %-10%, has a lot of negative effects on LED lamp beads, shortening the service life of LED
